I was surprised to see that the Boost distribution doesn't have the "atomic" operations library. I expected it to be part of the Threading, modeled on the C++0x draft. I found http://www.chaoticmind.net/~hcb/projects/boost.atomic/ via Google, from 2009. But N3225=10-0215 (is there a later Draft available ?) §29.2 shows lots of change bars, and the <atomic> header seems completely redone, it appears to make everything nicely templatated. I wonder if this is at all up-to-date, or why it's not already more officially part of Boost. Does anybody know? More to the point, I want to write some code that is portable across platforms, including emerging platforms like tablets which I expect will be more varied in their CPU architecture. I've been spoiled with writing x86-only for so many years! It makes sense to use the constructs that will be shipped with the compiler some day. So, where can I find that? —John
